STK Performance Valve Train Products (VTP's) are manufactured from the finest Quality Materials available and have been Developed & Tested under severe Motorsport conditions.

To ensure that your STK Performance VTP performs to its optimum ensure that the following “Break-In” Procedures are strictly adhered to:

STK Camshafts & STK Heavy Duty Camfollowers ( VW )

  • New camfollowers must be fitted with a new STK Camshaft (preferably STK Heavy Duty type #STK3).
  • Coat Camshaft & Camfollowers with Cam Lube during fitment.
  • Do not run on idle during the first 20 minutes of operation.
  • Run at 2500 - 3000Rpm . Do not run at high Rpm during this break-in period.
  • If any changes need to be made during this period switch off engine (Do Not Idle)

This break-in period will reduce the risk of Camshaft failure and prolong the life of your Camshaft.

 

STK Performance Hi-Rev Valve Springs

  • Ensure correct Spring Pressures, Spring Travel, Spring Height & Clearances.
  • On Initial Start-up limit between 1500 & 2000 Rpm until operating temperatures are achieved.
  • Shut-off engine and allow to cool to room temperature.

This break-in period will reduce the risk of Valve Spring failure and prolong the life of your Valve Springs.
